The audio diaspora is split on the subject of bass. Some audiophiles—surely the majority—consider the reproduction of low frequencies purely in terms of the weight and drama it adds to sounds with significant bass content. Others—the generalists—take a much wider view of the significance of extended bass response, noting that an audio system's ubiquitous high-pass filters are unusual in Nature and suggesting that this is one of the factors that separate, at the fundamental level, live sound from its poorer reproduced cousin. When John Atkinson wrote on this subject more than 10 years ago (Stereophile, November 1995, "As We See It"), he quoted a memorable line by Kal Rubinson that encapsulates this latter view: "Something in Nature abhors a capacitor."
Loudspeaker Cables & Interconnects Editor's Note: Rather than place cables in the usual "Recommended Components" classes, we've just listed those cables that members of the magazine's review team either have chosen to use on a long-term basis or have found to offer good value for money. They are therefore implicitly recommended. Where a cable has been found to have specific matching requirements or an identifiable sonic signature, it is noted in the text. "Try before you buy" is mandatory with cables; many dealers have a loaner stock to make this easier.
It is a truism that audiophiles love music. What distinguishes us (footnote 1) from the vast majority of music lovers is the importance we ascribe to the high-quality reproduction of recorded music. But what, exactly, constitutes high-quality sound reproduction? To many audiophiles, the answer relates to accuracy. Useful indices of accuracy include many of the parameters that editor John Atkinson routinely measures: flat frequency response, time and phase accuracy, and low distortion, to name a few. On the other hand, many audiophiles apparently have little interest in these aspects and instead seek nothing more—or less—than a romantic and pleasant sound. Such individuals are unfazed by demonstrable inaccuracies in their systems; as long as it sounds good to their ears, they are happy. Are these two schools of thought both compatible with the notion of high-end audio? If so, is one "more correct" than the other? Are they mutually exclusive? What brought this issue to mind was, of all things, a digital transport. Actually, two transports.
Much as I like the prospect of being able to grunt a heartfelt Je ne regrette rien immediately before expiring, I know there will be too many what-ifs and wish-I-hadn'ts to make that even remotely possible. But here is one missed opportunity that won't flash before me, because John Atkinson has granted me a second chance.

If there is one thing I've learned in almost 28 years (ouch) of audio writing, it's that audience reaction is fickle. Sometimes readers will swallow the most contentious pronouncements without indigestion, only to choke on throwaway lines you've invested with little importance. It just goes to confirm that human communication involves senders and receivers, and they aren't always in synchrony.
If you missed Part 1 of this article (Stereophile, January 2005), or it has faded in your memory, here's a résumé. (Readers who recall Part 1 with crystalline clarity, please skip to paragraph four.) The accurate measuring of loudspeakers requires that the measurements be taken in a reflection-free environment. Traditionally, this has meant that the speaker be placed atop a tall pole outdoors or in an anechoic chamber. Both of these options are hedged around with unwelcome implications of cost and practicality. To overcome these and allow quasi-anechoic measurements to be performed in normal, reverberant rooms, time-windowed measurement methods were developed that allow the user to analyze only that portion of the speaker's impulse response that arrives at the microphone ahead of the first room reflection. MLSSA from DRA Labs is the best-known measurement system to work on this principle, and both John Atkinson and I use it in the course of preparing our loudspeaker reviews.
Pick an expletive—one you would normally use to express deep intellectual frustration—but don't vocalize it. Hold it in reserve for a few minutes, letting it simmer to concentrate its intensity. I'll tell you when to let rip.

Looked at from one viewpoint, DVD-Audio and SACD appear to be exercises in sheer profligacy. In the case of DVD-A, why provide a maximum bandwidth almost five times what is conventionally taken to be the audible frequency range, and couple it to a dynamic-range capability far in excess of that achievable by the microphones used to record the sound? In the case of SACD, why provide a potential bandwidth in excess of 1.4MHz, only to fill more than 95% of it with quantization noise?
